7. Launch LG Bridge (LG PC Suite) depending on the one you have installed on the PC.

My LG G4 is stuck at boot logo instead of booting to recovery. What can I do?

Try another SD Card. You must use a first class grade one SD Card that's really fast.

My LG G4 is in recovery mode but LG Bridge or LG PC Suite does not detect it. Is something wrong?

Yes. Something is wrong. Check your USB Cord, USB Port or make sure that your drivers are properly installed. With each instance, you can try with another device to confirm.
